Do I need to take my cat to the vet?

Hi,Just wanted some opinions really. My 3 year old female cat is usually pretty sociable, and loves her food. However, for the past couple of days (especially today), she has just hidden under one of the beds upstairs and is not eating her food or coming out for cuddles or to say hello. This is really not like her.I was thinking she might not be feeling well, and wanted some peace and quiet (we have a toddler!). But she has been under the bed all day, and shows no signs of coming out. She doesn't appear to have been sick, and didn't seem injured when she came downstairs briefly this afternoon. She just doesn't want to be stroked, and hissed when I picked her up to give her a cuddle.Do you think I should take her to the vet tomorrow if she is no better?Thanks in advance.

Thanks for the fast replies. I will try her with some fish in a minute, as she has basically had nothing to eat all day. Not sure if she has drunk anything either, so I'll bring her a bit of water too. And I will get straight onto the vet in the morning.

Hiya! Just an update. Cat is a bit better today - took her to the vet earlier, who wasn't sure exactly what was wrong with her, but she had a high temp and appeared to be in pain. So she has a course of antibiotics and some anti-inflammatories, which start tomorrow (the vet gave her some shots today) - should be fun trying to get the doses down her

My cat will eat a tablet or capsule if it's in the middle of little ball of tuna mixed with enough cream cheese to make it sticky. If the anti-inflammatory is metacam then my girl doesn't notice it mixed in with a forkful of her normal food.

One of my darlings is on medication atm and I was amazed at how big the capsules are. She hated taking them so we resorted to opening them and sprinkling the powder on her food which has worked well. I wonder why the vet didn't just tell us to do that to begin with tbh.

Just managed to get liquid metacam down her by literally pinning her down and squirting it into her mouth. I've put the crushed synulox tab in some dried food with a bit of fish mixed in, but she seems to be avoiding that one for now.

Thanks for all the tips. Less traumatic today - for both of us. I put the liquid med on a tiny bit of chicken and she ate it all. And I have crushed the tablet and mixed it in her dried food, which has also been eaten. So no pinning down of the poor cat today! She is improving, but still not 100% yet.
